Certificate of Analysis

Transparency & trust

At Peak Peptides, every product comes with a Certificate of Analysis (COA). We believe you deserve to know exactly what you're putting into your body—purity, potency, and quality, verified by independent labs.

What is a COA?

A Certificate of Analysis is a document from an independent laboratory that confirms the identity, purity, and strength of a product. It shows test results for key compounds, contaminants, and heavy metals—so you can trust what's on the label.

We work with accredited labs and provide COAs for all our peptide products. When you buy from Peak Peptides, you're not just getting a supplement—you're getting verified quality and full transparency.
